Add function to configre LFPS sending for Panel Replay according to link training sequence in HAS document. This assumes we are using AUX Less always if it's supported by the sink and the source. v2: - drop HAS reference - replay kerneldoc comment with a generic comment - check display version in intel_lnl_mac_transmit_lfps Bspec: 68849 Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Link: https://lore.kernel.org/r/20250526120512.1702815-11-jouni.hogander@intel.com
